From a056ab8c7a00a0ffc52e9573bf01257004c2d08c Mon Sep 17 00:00:00 2001 From: Carlos Chinea Date: Fri, 16 Apr 2010 19:01:02 +0300 Subject: HSI: hsi: Introducing HSI framework Adds HSI framework in to the linux kernel. High Speed Synchronous Serial Interface (HSI) is a serial interface mainly used for connecting application engines (APE) with cellular modem engines (CMT) in cellular handsets. HSI provides multiplexing for up to 16 logical channels, low-latency and full duplex communication.

The ->direct_IO() method combines the existing fuse_direct_read/fuse_direct_write methods to implement O_DIRECT functionality. Reaching ->direct_IO() in the read path via generic_file_aio_read ensures proper synchronization with page cache with its existing framework. Reaching ->direct_IO() in the write path via fuse_file_aio_write is made to come via generic_file_direct_write() which makes it play nice with the page cache w.r.t other mmap pages etc. On files marked 'direct_io' by the filesystem server, IO always follows the fuse_direct_read/write path. There is no effect of fcntl(O_DIRECT) and it always succeeds. On files not marked with 'direct_io' by the filesystem server, the IO path depends on O_DIRECT flag by the application. This can be passed at the time of open() as well as via fcntl(). Note that asynchronous O_DIRECT iocb jobs are completed synchronously always (this has been the case with FUSE even before this patch) Signed-off-by: Anand Avati Reviewed-by: Jeff Moyer Signed-off-by: Miklos Szeredi diff --git a/fs/fuse/dir.c b/fs/fuse/dir.c index da37907..df5ac04 100644 --- a/fs/fuse/dir.c +++ b/fs/fuse/dir.c @@ -387,9 +387,6 @@ static int fuse_create_open(struct inode *dir, struct dentry *entry, if (fc->no_create) return -ENOSYS;

This hang can be triggered by sending small packets at a rate that was triggering Rx missed errors from the adapter while the internal Tx switch and at least one VF are enabled. This was all due to the fact that under heavy stress the Rx FIFO never drained below the flow control high water mark. This resulted in the Tx FIFO being head of line blocked due to the fact that it relies on the flow control high water mark to determine when it is acceptable for the Tx to place a packet in the Rx FIFO. The resolution for this is to set the FCRTH value to the RXPBSIZE - 32 so that even if the ring is almost completely full we can still place Tx packets on the Rx ring and drop incoming Rx traffic if we do not have sufficient space available in the Rx FIFO.

Having a global blkif_io_lock doesn't make sense given the use case, and it drastically hinders performance due to contention.

On OMAP4, recently a synchronisation bug is discovered by hardware team, which leads to incorrect timer value read from 32K sync timer IP when the IP is comming out of idle. The issue is due to the synchronization methodology used in the SYNCTIMER IP. The value of the counter register in 32kHz domain is synchronized to the OCP domain register only at count up event, and if the OCP clock is switched off, the OCP register gets out of synch until the first count up event after the clock is switched back -at the next falling edge of the 32kHz clock. Further investigation revealed that it applies to gptimer1 and watchdog timer2 as well which may run on 32KHz. This patch fixes the issue for all the applicable modules. The BUG has not made it yet to the OMAP errata list and it is applicable to OMAP1/2/3/4/5. OMAP1/2/3 it is taken care indirectly by autodeps. By enabling static depedency of wakeup clockdomain with MPU, as soon as MPU is woken up from lowpower state(idle) or whenever MPU is active, PRCM forces the OCP clock to be running and allow the counter value to be updated properly in the OCP clock domain. The bug is going to fixed in future OMAP versions.

The only reason for the distinction was for the special case of 'file' (which is assumed to be loopback device), was to reach inside the loopback device, find the underlaying file, and call fallocate on it. Fortunately "xen-blkback: convert hole punching to discard request on loop devices" removes that use-case and we now based the discard support based on blk_queue_discard(q) and extract all appropriate parameters from the 'struct request_queue'.

The assumption of having a higher threshold limit is that it would help de-sensitize the receiver (reduce phy errors) from continuous interference. But when we have a bursty interference where there are collisions and then free air time and if the receiver is desensitized too much, it will miss the normal packets too. Lets make use of chips specific min, nom and max limits always. This patch helps to improve the connection stability in congested networks.

But this doesn't happen in the failure pathway of rpm_suspend() when another autosuspend attempt is rescheduled.

Apparently some e1000 chips (not mine) are sensitive about the order of setting vlan filter and vlan stripping/inserting functionality.

Reported as: https://bugzilla.kernel.org/show_bug.cgi?id=42677 Test code pq_src array was grown by two elements to correspond with actual usage (IOP_ADMA_NUM_SRC_TEST+2), stack consumption was kept constant by modifying the pq_dest two element array which is only used when pq_src is referenced up to IOP_ADMA_NUM_SRC_TEST elements into the address of the new last two elements of the pq_src array.

Bug is 100% reproducible using hciattach and a disconnected serial port: 0. # hciattach -n ttyO1 any noflow 1. hci_dev_open called from hci_power_on grabs req lock 2. hci_init_req executes but device fails to initialise (times out eventually) 3. hci_dev_open is called from hci_sock_ioctl and sleeps on req lock 4. hci_uart_tty_close detaches protocol driver and cancels init req 5. hci_dev_open (1) releases req lock 6. hci_dev_open (3) grabs req lock, calls hci_init_req, which triggers oops when request is prepared in hci_uart_send_frame [ 137.201263] Unable to handle kernel NULL pointer dereference at virtual address 00000028 [ 137.209838] pgd = c0004000 [ 137.212677] [00000028] *pgd=00000000 [ 137.216430] Internal error: Oops: 17 [#1] [ 137.220642] Modules linked in: [ 137.223846] CPU: 0 Tainted: G W (3.3.0-rc6-dirty #406) [ 137.230529] PC is at __lock_acquire+0x5c/0x1ab0 [ 137.235290] LR is at lock_acquire+0x9c/0x128 [ 137.239776] pc : [] lr : [] psr: 20000093 [ 137.239776] sp : cf869dd8 ip : c0529554 fp : c051c730 [ 137.251800] r10: 00000000 r9 : cf8673c0 r8 : 00000080 [ 137.257293] r7 : 00000028 r6 : 00000002 r5 : 00000000 r4 : c053fd70 [ 137.264129] r3 : 00000000 r2 : 00000000 r1 : 00000000 r0 : 00000001 [ 137.270965] Flags: nzCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment kernel [ 137.278717] Control: 10c5387d Table: 8f0f4019 DAC: 00000015 [ 137.284729] Process kworker/u:1 (pid: 7, stack limit = 0xcf8682e8) [ 137.291229] Stack: (0xcf869dd8 to 0xcf86a000) [ 137.295776] 9dc0: c0529554 00000000 [ 137.304351] 9de0: cf8673c0 cf868000 d03ea1ef cf868000 000001ef 00000470 00000000 00000002 [ 137.312927] 9e00: cf8673c0 00000001 c051c730 c00716ec 0000000c 00000440 c0529554 00000001 [ 137.321533] 9e20: c051c730 cf868000 d03ea1f3 00000000 c053b978 00000000 00000028 cf868000 [ 137.330078] 9e40: 00000000 00000000 00000002 00000000 00000000 c00733f8 00000002 00000080 [ 137.338684] 9e60: 00000000 c02a1d50 00000000 00000001 60000013 c0969a1c 60000093 c053b96c [ 137.347259] 9e80: 00000002 00000018 20000013 c02a1d50 cf0ac000 00000000 00000002 cf868000 [ 137.355834] 9ea0: 00000089 c0374130 00000002 00000000 c02a1d50 cf0ac000 0000000c cf0fc540 [ 137.364410] 9ec0: 00000018 c02a1d50 cf0fc540 00000000 cf0fc540 c0282238 c028220c cf178d80 [ 137.372985] 9ee0: 127525d8 c02821cc 9a1fa451 c032727c 9a1fa451 127525d8 cf0fc540 cf0ac4ec [ 137.381561] 9f00: cf0ac000 cf0fc540 cf0ac584 c03285f4 c0328580 cf0ac4ec cf85c740 c05510cc [ 137.390136] 9f20: ce825400 c004c914 00000002 00000000 c004c884 ce8254f5 cf869f48 00000000 [ 137.398712] 9f40: c0328580 ce825415 c0a7f914 c061af64 00000000 c048cf3c cf8673c0 cf85c740 [ 137.407287] 9f60: c05510cc c051a66c c05510ec c05510c4 cf85c750 cf868000 00000089 c004d6ac [ 137.415863] 9f80: 00000000 c0073d14 00000001 cf853ed8 cf85c740 c004d558 00000013 00000000 [ 137.424438] 9fa0: 00000000 00000000 00000000 c00516b0 00000000 00000000 cf85c740 00000000 [ 137.433013] 9fc0: 00000001 dead4ead ffffffff ffffffff c0551674 00000000 00000000 c0450aa4 [ 137.441589] 9fe0: cf869fe0 cf869fe0 cf853ed8 c005162c c0013b30 c0013b30 00ffff00 00ffff00 [ 137.450164] [] (__lock_acquire+0x5c/0x1ab0) from [] (lock_acquire+0x9c/0x128) [ 137.459503] [] (lock_acquire+0x9c/0x128) from [] (_raw_spin_lock_irqsave+0x44/0x58) [ 137.469360] [] (_raw_spin_lock_irqsave+0x44/0x58) from [] (skb_queue_tail+0x18/0x48) [ 137.479339] [] (skb_queue_tail+0x18/0x48) from [] (h4_enqueue+0x2c/0x34) [ 137.488189] [] (h4_enqueue+0x2c/0x34) from [] (hci_uart_send_frame+0x34/0x68) [ 137.497497] [] (hci_uart_send_frame+0x34/0x68) from [] (hci_send_frame+0x50/0x88) [ 137.507171] [] (hci_send_frame+0x50/0x88) from [] (hci_cmd_work+0x74/0xd4) [ 137.516204] [] (hci_cmd_work+0x74/0xd4) from [] (process_one_work+0x1a0/0x4ec) [ 137.525604] [] (process_one_work+0x1a0/0x4ec) from [] (worker_thread+0x154/0x344) [ 137.535278] [] (worker_thread+0x154/0x344) from [] (kthread+0x84/0x90) [ 137.543975] [] (kthread+0x84/0x90) from [] (kernel_thread_exit+0x0/0x8) [ 137.552734] Code: e59f4e5c e5941000 e3510000 0a000031 (e5971000) [ 137.559234] ---[ end trace 1b75b31a2719ed1e ]--- Cc: stable Signed-off-by: Johan Hovold Acked-by: Marcel Holtmann Signed-off-by: Johan Hedberg diff --git a/drivers/bluetooth/hci_ldisc.c b/drivers/bluetooth/hci_ldisc.c index fd5adb4..98a8c05 100644 --- a/drivers/bluetooth/hci_ldisc.c +++ b/drivers/bluetooth/hci_ldisc.c @@ -299,11 +299,11 @@ static void hci_uart_tty_close(struct tty_struct *tty) hci_uart_close(hdev); if (test_and_clear_bit(HCI_UART_PROTO_SET, &hu->flags)) { - hu->proto->close(hu); if (hdev) { hci_unregister_dev(hdev); hci_free_dev(hdev); } + hu->proto->close(hu); } kfree(hu); -- cgit v0.10.2 From 94324962066231a938564bebad0f941cd2d06bb2 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 15 Mar 2012 14:48:41 +0100 Subject: Bluetooth: hci_core: fix NULL-pointer dereference at unregister Make sure hci_dev_open returns immediately if hci_dev_unregister has been called.

For this reason, introduce an alternative routine for read-locking umhelper_sem, usermodehelper_read_lock_wait(), that will wait for usermodehelper_disabled to be unset (possibly with a timeout) and make request_firmware_work_func() use it instead of usermodehelper_read_trylock().

Wysocki" Date: Wed, 28 Mar 2012 23:30:21 +0200 Subject: PM / Sleep: Move disabling of usermode helpers to the freezer The core suspend/hibernation code calls usermodehelper_disable() to avoid race conditions between the freezer and the starting of usermode helpers and each code path has to do that on its own. However, it is always called right before freeze_processes() and usermodehelper_enable() is always called right after thaw_processes(). For this reason, to avoid code duplication and to make the connection between usermodehelper_disable() and the freezer more visible, make freeze_processes() call it and remove the direct usermodehelper_disable() and usermodehelper_enable() calls from all suspend/hibernation code paths.

Wysocki" Date: Wed, 28 Mar 2012 23:30:28 +0200 Subject: PM / Sleep: Mitigate race between the freezer and request_firmware() There is a race condition between the freezer and request_firmware() such that if request_firmware() is run on one CPU and freeze_processes() is run on another CPU and usermodehelper_disable() called by it succeeds to grab umhelper_sem for writing before usermodehelper_read_trylock() called from request_firmware() acquires it for reading, the request_firmware() will fail and trigger a WARN_ON() complaining that it was called at a wrong time. However, in fact, it wasn't called at a wrong time and freeze_processes() simply happened to be executed simultaneously. To avoid this race, at least in some cases, modify usermodehelper_read_trylock() so that it doesn't fail if the freezing of tasks has just started and hasn't been completed yet. Instead, during the freezing of tasks, it will try to freeze the task that has called it so that it can wait until user space is thawed without triggering the scary warning. For this purpose, change usermodehelper_disabled so that it can take three different values, UMH_ENABLED (0), UMH_FREEZING and UMH_DISABLED. The first one means that usermode helpers are enabled, the last one means "hard disable" (i.e. the system is not ready for usermode helpers to be used) and the second one is reserved for the freezer. Namely, when freeze_processes() is started, it sets usermodehelper_disabled to UMH_FREEZING which tells usermodehelper_read_trylock() that it shouldn't fail just yet and should call try_to_freeze() if woken up and cannot return immediately. This way all freezable tasks that happen to call request_firmware() right before freeze_processes() is started and lose the race for umhelper_sem with it will be frozen and will sleep until thaw_processes() unsets usermodehelper_disabled. [For the non-freezable callers of request_firmware() the race for umhelper_sem against freeze_processes() is unfortunately unavoidable.] Reported-by: Stephen Boyd Signed-off-by: Rafael J.

Instead of creating a new kthread for each request_firmware_nowait() call just schedule the work on the system workqueue. This should avoid some overhead in forking new threads when they're not strictly necessary. Signed-off-by: Stephen Boyd Acked-by: Greg Kroah-Hartman Signed-off-by: Rafael J.

For example, pm_qos_update_request_timeout(req, 100, 1000), means that QoS request on req with value 100 will be active for 1000 microseconds. After 1000 microseconds, the QoS request thru req is reset. If there were another pm_qos_update_request(req, x) during the 1000 us, this new request with value x will override as this is another request on the same req handle. A new request on the same req handle will always override the previous request whether it is the conventional request or it is the new timeout request.

If the interrupt is delivered while marked disabled, the low level interrupt handler masks it and marks it pending. This is important for detecting wakeup interrupts during suspend and for edge type interrupts to avoid losing interrupts. fixup_irqs() moves the interrupts away from an offlined cpu. For certain interrupt types it needs to mask the interrupt line before changing the affinity. After affinity has changed the interrupt line is unmasked again, but only if it is not marked disabled. This breaks the lazy irq disable semantics and causes problems in suspend as the interrupt can be lost or wakeup functionality is broken. Check irqd_irq_masked() instead of irqd_irq_disabled() because irqd_irq_masked() is only set, when the core code actually masked the interrupt line. If it's not set, we unmask the interrupt and let the lazy irq disable logic deal with an eventually incoming interrupt.

This is because the test suite did not fully implement the behavior of a real debugger. A real debugger tracks the state of what thread it asked to single step and can correctly continue other threads of execution or conditionally stop while waiting for the original thread single step request to return. Below is a simple method to cause a fatal kernel oops with the kgdb test suite on a 4 processor x86 system: while [ 1 ] ; do ls > /dev/null 2> /dev/null; done& while [ 1 ] ; do ls > /dev/null 2> /dev/null; done& while [ 1 ] ; do ls > /dev/null 2> /dev/null; done& while [ 1 ] ; do ls > /dev/null 2> /dev/null; done& echo V1I1F1000 > /sys/module/kgdbts/parameters/kgdbts Very soon after starting the test the kernel will oops with a message like: kgdbts: BP mismatch 3b7da66480 expected ffffffff8106a590 WARNING: at drivers/misc/kgdbts.c:303 check_and_rewind_pc+0xe0/0x100() Call Trace: [] check_and_rewind_pc+0xe0/0x100 [] validate_simple_test+0x25/0xc0 [] run_simple_test+0x107/0x2c0 [] kgdbts_put_char+0x18/0x20 The warn will turn to a hard kernel crash shortly after that because the pc will not get properly rewound to the right value after hitting a breakpoint leading to a hard lockup. This change is broken up into 2 pieces because archs that have hw single stepping (2.6.26 and up) need different changes than archs that do not have hw single stepping (3.0 and up). This change implements the correct behavior for an arch that supports hw single stepping. A minor defect was fixed where sys_open should be do_sys_open for the sys_open break point test. This solves the problem of running a 64 bit with a 32 bit user space. The sys_open() never gets called when using the 32 bit file system for the kgdb testsuite because the 32 bit binaries invoke the compat_sys_open() call leading to the test never completing. In order to mimic a real debugger, the kgdb test suite now tracks the most recent thread that was continued (cont_thread_id), with the intent to single step just this thread. When the response to the single step request stops in a different thread that hit the original break point that thread will now get continued, while the debugger waits for the thread with the single step pending.

The debug_core only uses the the probe_kernel_write() to install breakpoints, but this is not enough for all the archs. Some arch such as x86 need to use text_poke() in order to install a breakpoint into a read only page. Passing the kgdb_bpt structure to kgdb_arch_set_breakpoint() and kgdb_arch_remove_breakpoint() allows other archs to set the type variable which indicates how the breakpoint was installed.

For this particular patch, it will apply cleanly and has been tested all the way back to 2.6.36. The kprobes code uses the text_poke() function which accommodates writing a breakpoint into a read-only page. The x86 kgdb code can solve the problem similarly by overriding the default breakpoint set/remove routines and using text_poke() directly. The x86 kgdb code will first attempt to use the traditional probe_kernel_write(), and next try using a the text_poke() function. The break point install method is tracked such that the correct break point removal routine will get called later on. Cc: x86@kernel.org Cc: Thomas Gleixner Cc: Ingo Molnar Cc: H.

Its effect was to replace the use of the HLT instruction inside default_idle() with cpu_relax() - essentially it turned off the use of HLT. This workaround was commented in the code as: "disable hlt during certain critical i/o operations" "This halt magic was a workaround for ancient floppy DMA wreckage. It should be safe to remove." H. Peter Anvin additionally adds: "To the best of my knowledge, no-hlt only existed because of flaky power distributions on 386/486 systems which were sold to run DOS. Since DOS did no power management of any kind, including HLT, the power draw was fairly uniform; when exposed to the much hhigher noise levels you got when Linux used HLT caused some of these systems to fail. They were by far in the minority even back then." Alan Cox further says: "Also for the Cyrix 5510 which tended to go castors up if a HLT occurred during a DMA cycle and on a few other boxes HLT during DMA tended to go astray. Do we care ? I doubt it. The 5510 was pretty obscure, the 5520 fixed it, the 5530 is probably the oldest still in any kind of use." So, let's finally drop this.

Presently there's no SHmedia support plugged in for the dwarf unwinder. While it's trivial to provide an SHmedia version of dwarf_read_arch_reg(), the general sh64 case is more complicated in that the TLB miss handler uses a locked down set of registers for optimization (including the frame pointer) which we need for the unwind table generation. While freeing up the frame pointer for use in the TLB miss handler is reasonably straightforward, it's still more trouble than it's worth, so we simply restrict the unwinder to 32-bit for now.

This commit doesn't add any driver support, it is simply and agreed upon starting point so we can work towards merging driver support for the next merge window. Current drivers with work done are nouveau, i915, udl, exynos and omap. The main APIs exposed to userspace allow translating a 32-bit object handle to a file descriptor, and a file descriptor to a 32-bit object handle. The flags value is currently limited to O_CLOEXEC. Acknowledgements: Daniel Vetter: lots of review Rob Clark: cleaned up lots of the internals and did lifetime review. v2: rename some functions after Chris preferred a green shed fix IS_ERR_OR_NULL -> IS_ERR v3: Fix Ville pointed out using buffer + kmalloc v4: add locking as per ickle review v5: allow re-exporting the original dma-buf (Daniel) Reviewed-by: Daniel Vetter Reviewed-by: Rob Clark Reviewed-by: Sumit Semwal Reviewed-by: Inki Dae Acked-by: Ben Widawsky Signed-off-by: Dave Airlie diff --git a/drivers/gpu/drm/Kconfig b/drivers/gpu/drm/Kconfig index cc11488..e354bc0 100644 --- a/drivers/gpu/drm/Kconfig +++ b/drivers/gpu/drm/Kconfig @@ -9,6 +9,7 @@ menuconfig DRM depends on (AGP || AGP=n) && !EMULATED_CMPXCHG && MMU select I2C select I2C_ALGOBIT + select DMA_SHARED_BUFFER help Kernel-level support for the Direct Rendering Infrastructure (DRI) introduced in XFree86 4.0.

Unfortunately, this has probably never worked, since ptrace_read_user predicates reading on off < sizeof(struct user), returning -EIO otherwise. This patch moves the offset size check until after we have tried to match it against either a magic value or an offset into pt_regs.

E.g.: - to enable rc6, i915_enable_rc6=1 - to enable rc6 and deep rc6, i915_enable_rc6=3 - to enable rc6 and deepest rc6, use i915_enable_rc6=5 - to enable rc6, deep and deepest rc6, use i915_enable_rc6=7 Please keep in mind that the deepest RC6 state really should NOT be used by default, as it could potentially worsen the issues with deep RC6. So do enable it only when you know what you are doing. However, having it around could help solving possible future rc6-related issues and their debugging on user machines. Note that this changes behavior - previously, value of 1 would enable both RC6 and deep RC6. Now it should only enable RC6 and deep/deepest RC6 stages must be enabled manually. v2: address Chris Wilson comments and clean up the code.

Now that we have discovered that RC6 issues are triggered by RC6+ state, let's try to disable it by default. Plain RC6 is the one responsible for most energy savings, and so far it haven't given any problems - at least, none we are aware of. So with this, when i915_enable_rc6=-1 (e.g., the default value), we'll attempt to enable plain RC6 only on SNB. For Ivy Bridge, the behavior stays the same as always - we enable both RC6 and deep RC6. Note that while this exact patch does not has explicit tested-by's, the equivalent settings were fixed in 3.3 kernel by a smaller patch. And it has also received considerable testing through Canonical RC6 task-force testing at https://wiki.ubuntu.com/Kernel/PowerManagementRC6. Up to date, it looks like all the known issues are gone. v2: improve description and reference a couple of open bugs related to RC6 which seem to be fixed with this change.

This might happen if a previous leave request for the attribute has not yet been followed by a PDU transmission (or, if the application previously issued a join request for the attribute and is now issuing another one, without having issued a leave request). If garp_attr_create finds an existing attribute having the same values, return the address to it. Its state will then get updated (i.e., if it was in a leaving state, it will move into a non-leaving state and not get deleted during the next PDU transmission).

However in IPv6, RTA_IIF is not interpreted in the same way: 'inet6_rtm_getroute()' always calls 'ip6_route_output()', regardless the RTA_IIF attribute. As a result, in IPv6 there's no way to use RTM_GETROUTE in order to look for a route as if a packet was received on a specific interface. Fix 'inet6_rtm_getroute()' so that RTA_IIF is interpreted as "lookup a route as if a packet was received on the specified interface", similar to IPv4's 'inet_rtm_getroute()' interpretation.

In cfq, when we calculate a time slice for a process(or a cfqq to be precise), we have to consider the cfq_target_latency so that all the sync request have an estimated latency(300ms) and it is controlled by cfq_target_latency. But in some hadoop test, we have found that if there are many processes doing sequential read(24 for example), the throughput is bad because every process can only work for about 25ms and the cfqq is switched. That leads to a higher disk seek. We can achive the good throughput by setting low_latency=0, but then some read's latency is too much for the application. So this patch makes cfq_target_latency tunable through sysfs so that we can tune it and find some magic number which is not bad for both the throughput and the read latency.

However it doesn't clear the bios->data pointer between the iterations. In some cases, the shadow() method will fail and not update bios->data at all, which will cause us to "score" the old data and incorrectly attribute that score to the new method. This can cause double frees later when disposing of the unused data. Additionally, we were not freeing the data for methods that fail the score test (we only freed when a "best" is superseeded, not when the new method has a lower score than the exising "best").

Make sure to tag every line of userspace backtrace output if we actually have the mmap_sem, since that way if there's no tag, we know that it's because we couldn't trylock the semaphore. Stop doing a TLB flush and examining page tables during backtrace. Instead, just trust that __copy_from_user_inatomic() will properly fault and return a failure, which it should do in all cases. Fix a latent bug where the backtracer would directly examine a signal context in user space, rather than copying it safely to kernel memory first. This meant that a race with another thread could potentially have caused a kernel panic. Guard against unaligned sp when trying to restart backtrace at an interrupt or signal handler point in the kernel backtracer. Report kernel symbolic information for the call instruction rather than for the following instruction. We still report the actual numeric address corresponding to the instruction after the call, for the sake of consistency with the normal expectations for stack backtracers.

I suspect it had attempted suspend immediately after resuming and lost a race. During that msleep(10);, a new suspend cycle must have started and changed ->suspend_state to SUSPEND_PENDING, so it was never seen to be SUSPEND_DONE and the loop could never exited. It would have moved on to SUSPEND_ACKTO but never been able to reach SUSPEND_DONE. So change the loop to only run while SUSPEND_ACKED rather than until SUSPEND_DONE. This is much safer.

Currently __kvmppc_vcore_entry doesn't save and restore the CR, leading to CR2--CR4 getting corrupted with guest values, possibly leading to incorrect behaviour in its caller.

This patch requires LSMs to declare the LSM specific portion separately rather than doing it in a union. Thus each LSM can be responsible for shrinking their portion and don't have to pay a penalty just because other LSMs have a bigger space requirement.

To do this I'm going to move anything larger than 2 void * ptrs to it's own structure and require it to be declared separately on the calling stack. Thus hot paths which don't need more than a couple pointer don't have to declare space to hold large unneeded structures. I could get this down to one void * by dealing with the key struct and the struct path. We'll see if that is helpful after taking care of networking.

We end up seeing large bursts of packets on just *one* slave device, rather than using the full available bandwidth over all slaves. This patch fixes the problem by *not* unconditionally stopping the queue in ppp_start_xmit(). It adds a return value from ppp_xmit_process() which indicates whether the queue should be stopped or not. It *doesn't* remove the call to netif_wake_queue() from ppp_xmit_process(), because other code paths (especially from ppp_output_wakeup()) need it there and it's messy to push it out to the other callers to do it based on the return value. So we leave it in place — it's a no-op in the case where the queue wasn't stopped, so it's harmless in the TX path. Signed-off-by: David Woodhouse Signed-off-by: David S.

(assuming PAGE_SIZE=4096) The call to tcp_push() at the end of do_tcp_sendpages() forces an immediate xmit when pipe is not already filled, and tso_fragment() try to split these skb to MSS multiples. 4096 bytes are usually split in a skb with 2 MSS, and a remaining sub-mss skb (assuming MTU=1500) This makes slow start suboptimal because many small frames are sent to qdisc/driver layers instead of big ones (constrained by cwnd and packets in flight of course) In fact, applications using sendmsg() (adding an additional memory copy) instead of vmsplice()/splice()/sendfile() are a bit faster because of this anomaly, especially if serving small files in environments with large initial [c]wnd. Call tcp_push() only if MSG_MORE is not set in the flags parameter. This bit is automatically provided by splice() internals but for the last page, or on all pages if user specified SPLICE_F_MORE splice() flag. In some workloads, this can reduce number of sent logical packets by an order of magnitude, making zero-copy TCP actually faster than one-copy :) Reported-by: Tom Herbert Cc: Nandita Dukkipati Cc: Neal Cardwell Cc: Tom Herbert Cc: Yuchung Cheng Cc: H.K.

Previously, a series of 'change' commands followed by a call to ixgbe_dcbnl_set_all() would always be handled as a HW change - even if the net change was zero. This patch checks for this case of no actual change and skips going through the HW set process. Without this fix, the link could reset and result in a link flap. The core change in this patch is to check for changes in the ixgbe_copy_dcb_cfg() routine - and return a bitmask of detected changes. The other places where changes were detected previously can be removed.

This patch also fixes the return value of ip101a_config_init. Without this patch ip101a_config_init returns 2 which is not an error accroding to IS_ERR and the mac driver will continue accessing 2 as valid pointer to phy_dev resulting in memory fault.

The current code does the following: a) checks if clk is unused b) holds lock c) disables clk d) unlocks Between (a) and (b) being executed on CPU0, It is possible to have a driver executing on CPU1 which could do a get_sync->clk_get (and increase the use_count) of the clock which was just about to be disabled by clk_disable_unused.

Struct sctp_event_subscribe needs to be extended by an u8 for every new event or notification type that is added. This obviously makes getsockopt fail for binaries that are compiled against an older versions of which do not contain all event types. This patch changes getsockopt behaviour to no longer return an error if not enough bytes are being provided by the user. Instead, it returns as much of sctp_event_subscribe as fits into the provided buffer. This leads to the new behavior that users see what they have been aware of at compile time.

This particular allocation is used for large packet fragments that may have a size of 512, 1024, 4096 or fill the whole allocation. So, a minimum size of 16384 is good enough and will be the same size that is used in architectures of 4KiB sized pages. This will avoid allocation failures that we see when the system is under stress, but still has plenty of memory, like the one below. This will also allow us to set the interface MTU to higher values like 9000, which was not possible on ppc64 without this patch.

The original patch from Richard Weinberger (https://lkml.org/lkml/2011/3/14/362) alters dmesg_restrict as expected, and so the patch seems to have been misapplied.

PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.

This keeps the device active unnecessarily. This can be especially problematic when the ASoC platform device and DAI device are the same device. The distinction between OFF and STANDBY is likely not relevant for ASoC platform drivers, since they aren't analog devices. So, solve this issue by hard-coding idle_bias_off = 1 for all ASoC platform devices. If this turns out to be a problem, this value could be sourced from the snd_soc_platform_driver, similarly to soc_probe_codec(). Note: Prior to this change, this caused a large (10) runtime_active count for the Tegra I2S controller even when not in use, and a leak in that value as streams were started and stopped. This change probably hides a bug.

When a process exec()'s, all the maps are retired, but we keep the hist entries around which hold references to those outdated maps. If the same library gets mapped in for which we have hist entries, a new map will be created. But when we take a perf entry hit within that map, we'll find the existing hist entry with the older map. This causes symbol translations to be done incorrectly. For example, the perf entry processing will lookup the correct uptodate map entry and use that to calculate the symbol and DSO relative address. But later when we update the histogram we'll translate the address using the outdated map file instead leading to conditions such as out-of-range offsets in symbol__inc_addr_samples(). Therefore, update the map of the hist_entry dynamically at lookup/ creation time. Signed-off-by: David S.

Quoted comments from Al: "Note that unregister_filesystem() in module init is *always* wrong; it's not an issue here (it's done too early to care about and realistically the box is not going anywhere - it'll panic when attempt to exec /sbin/init fails, if not earlier), but it's a damn bad example. Consider a normal fs module. Somebody loads it and in parallel with that we get a mount attempt on that fs type. It comes between register and failure exits that causes unregister; at that point we are screwed since grabbing a reference to module as done by mount is enough to prevent exit, but not to prevent the failure of init. As the result, module will get freed when init fails, mounted fs of that type be damned." So remove it.

This has not been an issue before, because mem_cgroup_uncharge_swap was not called from !CONFIG_SWAP context. But Hugh Dickins has a cleanup patch to call __mem_cgroup_commit_charge_swapin which is defined also for !CONFIG_SWAP. Let's move both the empty definition and declaration outside of the CONFIG_SWAP block to avoid the following compilation error: mm/memcontrol.c: In function '__mem_cgroup_commit_charge_swapin': mm/memcontrol.c:2837: error: implicit declaration of function 'mem_cgroup_uncharge_swap' if CONFIG_SWAP is disabled.

Fix that by checking for both and return in both cases -ERANGE, so that tools can communicate this to the user properly, or if they chose so, to abort. This problem was reported previously but the fixes involved either doing what was being done for the > end case, i.e. silently drop the sample, returning 0, or aborting at this function, which is in a lib (or better, is slated to be at some point) and shouldn't abort. The 'report' tool already checks this value and uses pr_debug to warn the user. This patch makes the 'top' tool check it too and warn once per map where such range problem takes place.

This case can be represented using the sdhci quirk SDHCI_QUIRK_NONSTANDARD_CLOCK instead of using an additional enum type definition 'clk_types'. Hence, usage of clk_type member in platform data is removed and the sdhci quirk is used. In addition to that, since this qurik is SoC specific, driver data is introduced to represent controllers on SoC's that require this quirk.

Wysocki" Date: Sun, 1 Apr 2012 00:34:58 -0400 Subject: mmc: sdio: Use empty system suspend/resume callbacks at the bus level Neil Brown reports that commit 35cd133c PM: Run the driver callback directly if the subsystem one is not there breaks suspend for his libertas wifi, because SDIO has a protocol where the suspend method can return -ENOSYS and this means "There is no point in suspending, just turn me off". Moreover, the suspend methods provided by SDIO drivers are not supposed to be called by the PM core or bus-level suspend routines (which aren't presend for SDIO). Instead, when the SDIO core gets to suspend the device's ancestor, it calls the device driver's suspend function, catches the ENOSYS, and turns the device off. The commit above breaks the SDIO core's assumption that the device drivers' callbacks won't be executed if it doesn't provide any bus-level callbacks. If fact, however, this assumption has never been really satisfied, because device class or device type suspend might very well use the driver's callback even without that commit. The simplest way to address this problem is to make the SDIO core tell the PM core to ignore driver callbacks, for example by providing no-operation suspend/resume callbacks at the bus level for it, which is implemented by this change.

If we reach this point in the loop it means that we crossed a tick boundary since we grabbed the "now" timestamp, so at this point "now" refers to a time in the old jiffy, so using the old value for "now" is incorrect, and is likely to give us a stale jiffies value. In particular, the first time through the loop the tick_do_update_jiffies64(now) call is always a no-op, since the caller, tick_nohz_restart_sched_tick(), will have already called tick_do_update_jiffies64(now) with that "now" value. Note that tick_nohz_stop_sched_tick() already uses the correct approach: when we notice we cross a jiffy boundary, grab a new timestamp with ktime_get(), and *then* update jiffies.

That function calls mp_find_ioapics to get the 'struct ioapic' structure - which along with the mp_irq[x] is used to figure out the default values and the polarity/trigger overrides. Since the mp_find_ioapics now returns -1 [b/c the IOAPIC is filled with 0xffffffff], the acpi_get_override_irq() stops trying to lookup in the mp_irq[x] the proper INT_SRV_OVR and we can't install the SCI interrupt. The proper fix for this is going in v3.5 and adds an x86_io_apic_ops struct so that platforms can override it. But for v3.4 lets carry this work-around. This patch does that by providing a slightly different variant of the fake IOAPIC entries.

The library code uses urb->dev to determine whether or nor an URB is currently active; the completion handler sets urb->dev to NULL. However the core unlinking routines need to use urb->dev. Since unlinking always racing with completion, the completion handler must not clear urb->dev -- it can lead to invalid memory accesses when a transfer has to be cancelled. This patch fixes the problem by getting rid of the lines that clear urb->dev after urb has been submitted. As a result we may end up trying to unlink an URB that failed in submission or that has already completed, so an extra check is added after each unlink to avoid printing an error message when this happens. The checks are updated in both sg_complete() and sg_cancel(), and the second is updated to match the first (currently it prints out unnecessary warning messages if a device is unplugged while a transfer is in progress).

It's architecture-specific for two reasons: - some of the functions are likely to want architecture-specific implementations. Even if the current code happens to be "generic" in the sense that it should work on any little-endian machine, it's likely that the "multiply by a big constant and shift" implementation is less than optimal for an architecture that has a guaranteed fast bit count instruction, for example. - I expect that if architectures like sparc want to start playing around with this, we'll need to abstract out a few more details (in particular the actual unaligned accesses). So we're likely to have more architecture-specific stuff if non-x86 architectures start using this.

What used to happen is that the events inherited the initial tuning parameters from the FE_SET_FRONTEND call. However, the fepriv->parameters_out struct is now not initialised until the status contains the FE_HAS_LOCK bit. You might argue that this behaviour is intentional, except that if an application other than xine uses the DVB adapter and manages to set the parameters_out.frequency field to something other than zero, then xine no longer has any problems until either the adapter is replugged or the kernel modules reloaded. This can only mean that the fepriv->parameters_out struct still contains the (stale) tuning information from the previous application.

No, this is the correct patch: RADIO_MAXIRADIO should be treated just like RADIO_SF16FMR2, I just didn't realize at the time that it had to be added as a SND_TEA575X dependency.

If a DQBUF call arrives in-between, uvc_video_clock_update() will be called with a NULL clock samples buffer, leading to a crash. This occurs very frequently when using the webcam with the flash browser plugin. Move clock initialization/cleanup to uvc_video_enable() in order to free the clock samples buffer after the queue is stopped. Make sure the clock is reset at resume time to avoid miscalculating timestamps.

SER_RS485_RX_DURING_TX is not set as we do not want to receive the data we transmit (our transceiver will receive transmitted data). Although the current driver attempts to disable and enable the receiver at the appropriate points, incoming data is still loaded into the receive register causing our code to receive the very last byte that was sent once the receiver is enabled. I ran this by Atmel support and they wrote: "The issue comes from the fact that you disable the PDC/DMA Reception and not the USART Reception channel. In your case, the[n] you will still receive data into the USART_RHR register, and maybe you [h]ave the overrun flag set. So please disable the USART reception channel." The following patch should force the driver to enable/disable the receiver via RXEN/RXDIS fields of the USART control register. It fixed the issue I was having.

This tried to enforce the semantics of one interrupt per iir read of the THRE (transmit-hold empty) status, but events from other sources (particularly modem status) defeat this guarantee. This change also broke 8250_pci suspend/resume support as pciserial_resume_ports() re-runs .init() quirks, but does not run .exit() quirks in pciserial_suspend_ports() leading to reports like: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:16.3/msi_irqs' ...and a subsequent crash. The mismatch of init/exit at suspend/resume seems like a bug in its own right.

The semantic of UPF_IIR_ONCE is only guaranteed to workaround the race condition in the kt serial's iir register if the only source of interrupts is THRE (fifo-empty) events. An modem status event at the wrong time can again cause an iir read to drop the 'empty' status leading to a hang. So, revert this in preparation for using the existing "I don't trust my iir register" workaround in the 8250 core (UART_BUG_THRE).

If we disable the pipe, and then try to execute a WAIT_FOR_EVENT it will block indefinitely and cause a GPU hang. We attempted to fix this in commit 85345517fe6d4de27b0d6ca19fef9d28ac947c4a (drm/i915: Retire any pending operations on the old scanout when switching) for the case of mode switching, but this leaves the condition where we are switching off the pipe vulnerable. There still remains the race condition were a display may be unplugged, switched off by the core, a uevent sent to notify the DDX and the DDX may issue a WAIT_FOR_EVENT before it processes the uevent. This window does not exist if the pipe is only switched off in response to the uevent. Time to make sure that is so...

Unloading and reloading a serial driver while a serial device is plugged in causes errors because of the code in usb_serial_disconnect() that tries to make sure the port_remove method is called. With the new order of driver registration introduced in the 3.4 kernel, this is definitely not the right thing to do (if indeed it ever was). The patch removes that whole section code, along with the mechanism for keeping track of each port's registration state, which is no longer needed. The driver core can handle all that stuff for us.

When the system is going to sleep, we should ignore errors in powering down USB devices, because they don't really matter. The devices will go to low power anyway when the entire USB bus gets suspended (except for SuperSpeed devices; maybe they will need special treatment later). However we should not ignore errors in suspending root hubs, especially if the error indicates that the suspend raced with a wakeup request. Doing so might leave the bus powered on while the system was supposed to be asleep, or it might cause the suspend of the root hub's parent controller device to fail, or it might cause a wakeup request to be ignored. The patch fixes the problem by ignoring errors only when the device in question is not a root hub.

An xor is still required to determine which lines have changed. The count was only being incremented if the line was high. The only reason TIOCMIWAIT still worked was because the status packet is repeated every 1ms, so the count was always changing. The wakeup itself still ran based on the status lines changing. This change fixes handling of updates to the modem status lines and allows multiple processes to use TIOCMIWAIT concurrently. Tested with two processes waiting on different status lines being toggled independently.

If a wakeup event occurs while a root hub is suspending, it might not cause the suspend to fail. Although the host controller drivers check for pending wakeup events at the start of their bus_suspend routines, they generally do not check for wakeup events while the routines are running. In addition, if a wakeup event occurs any time after khubd is frozen and before the root hub is fully suspended, it might not cause a system sleep transition to fail. For example, the host controller drivers do not fail root-hub suspends when a connect-change event is pending. To fix both these issues, this patch causes hcd_bus_suspend() to query the controller driver's hub_status_data method after a root hub is suspended, if the root hub is enabled for wakeup. Any pending status changes will count as wakeup events, causing the root hub to be resumed and the overall suspend to fail with -EBUSY. A significant point is that not all events are reflected immediately in the status bits. Both EHCI and UHCI controllers notify the CPU when remote wakeup begins on a port, but the port's suspend-change status bit doesn't get set until after the port has completed the transition out of the suspend state, some 25 milliseconds later. Consequently, the patch will interpret any nonzero return value from hub_status_data as indicating a pending event, even if none of the status bits are set in the data buffer. Follow-up patches make the necessary changes to ehci-hcd and uhci-hcd.

It turns out the lowmemorykiller actually doesn't need this notifier at all. It's used to prevent unnecessary killing by waiting for a thread to exit as a result of lowmem_shrink(), however, it's possible to do this in the same way the kernel oom killer works by setting TIF_MEMDIE and avoid killing if we're still waiting for it to exit. The kernel oom killer will already automatically set TIF_MEMDIE for threads that are attempting to allocate memory that have a fatal signal. The thread selected by lowmem_shrink() will have such a signal after the lowmemorykiller sends it a SIGKILL, so this won't result in an unnecessary use of memory reserves for the thread to exit. This has the added benefit that we don't have to rely on CONFIG_PROFILING to prevent needlessly killing tasks.

The code would save and restore some GPRs around the calls to the C lockdep code, however, it tries to be too smart for its own good and restores some of the GPRs from the exception frame (as saved there on exception entry). However, for page faults, we do replace those GPRs with arguments to do_page_fault before we call transfer_to_handler and so restoring from the exception frame is plain wrong in this case. This was fine as long as we didn't touch the interrupt state when taking page fault, but when I started doing it, it would trigger the lockdep calls and the bug. This fixes it by cleaning up that code a bit. It did create a small stack frame for the sake of backtraces, so let's make it a bit bigger and use it to save and restore the stuff we care about.

Since the current code does not re-read the VIC_IRQ_STATUS register, this can lead to multiple invocations of the same interrupt handler and spurious interrupts to be reported. This patch changes the VIC interrupt dispatching code to re-read the status register each time, avoiding duplicate invocations of the same handler.

This breaks the platforms which need broadcast device oneshot services during deep idle states. tick_broadcast_oneshot_control() thinks that it is in periodic mode and fails to take proper decisions based on the CLOCK_EVT_NOTIFY_BROADCAST_[ENTER, EXIT] notifications during deep idle entry/exit. Fix this by tracking the broadcast device mode as 'TICKDEV_MODE_ONESHOT', before leaving the broadcast HW device in shutdown mode if there are no active requests for the moment.

However, tcp_error() relies on the "dataoff" offset to the TCP header, calculated by ipv4_get_l4proto(). But ipv4_get_l4proto() does not check bogus ihl values in IPv4 packets, which then can slip through tcp_error() and get caught at the TCP options parsing routines. The patch fixes ipv4_get_l4proto() by invalidating packets with bogus ihl value. The patch closes netfilter bugzilla id 771.

We were previously setting the GL_NOCACHE bit when the glock was released. That forced the rindex inode to be invalidated, which caused us to re-read rindex at the next access. However, it caused the glock to be unnecessarily bounced around the cluster. This patch allows the glock to remain cached, but it still causes the rindex to be re-read once it has been written to by gfs2_grow. Ben and I have tested single-node gfs2_grow cases and I've tested clustered gfs2_grow cases on my four-node cluster.

Avoid these confusing runtime pm dependences by making musb_init_controller() and omap2430_musb_init() do their own runtime get/put pairs; also cover error paths. Remove unneeded runtime_pm_put in omap2430_remove too. isp1704_charger crash that motivated 772aed45b604 will be fixed by following patch.

Therefore, we need to move prime status stage from complete irq routine to the place where the data stage has just primed, or the host will never get ACK for status stage. The above issue has been described at USB2.0 spec chapter 8.5.3.3. - After adding prime status stage just after prime the data stage, there is a potential problem when the status dTD is added before the data stage has primed by hardware. The reason is the device's dTD descriptor has NO direction bit, if data stage (IN) prime hasn't finished, the status stage(OUT) dTD will be added at data stage dTD's Next dTD Pointer, so when the data stage transfer has finished, the status dTD will be primed as IN by hardware, then the host will never receive ACK from the device side for status stage. - Delete below code at fsl_ep_queue: /* Update ep0 state */ if ((ep_index(ep) == 0)) udc->ep0_state = DATA_STATE_XMIT; the udc->ep0_state will be updated again after udc->driver->setup finishes.

The intent in the code was to only use the 'm' measurement if it was a new minimum. However, since 'm' had not yet been shifted left 3 bits but 'new_sample' had, this comparison would nearly always succeed, leading us to erroneously set our receive-side RTT estimate to the 'm' sample when that sample could be nearly 8x too high to use. The overall effect is to often cause the receive-side RTT estimate to be significantly too large (up to 40% too large for brief periods in my tests).

In commit 4bbdd45a (irq_domain/powerpc: eliminate irq_map; use irq_alloc_desc() instead) code was added that ignores error returns from irq_alloc_desc_from() by (silently) casting the return value to unsigned. The negitive value error return now suddenly looks like a valid irq number. Commits cc79ca69 (irq_domain: Move irq_domain code from powerpc to kernel/irq) and 1bc04f2c (irq_domain: Add support for base irq and hwirq in legacy mappings) move this code to its current location in irqdomain.c The result of all of this is a null pointer dereference OOPS if one of the error cases is hit. The fix: Don't cast away the negativeness of the return value and then check for errors.

Partially revert the above git commit and go back to s390 specific page table flush code. For s390 the TLB can contain three types of entries, "normal" TLB page-table entries, TLB combined region-and-segment-table (CRST) entries and real-space entries. Linux does not use real-space entries which leaves normal TLB entries and CRST entries. The CRST entries are intermediate steps in the page-table translation called translation paths. For example a 4K page access in a three-level page table setup will create two CRST TLB entries and one page-table TLB entry. The advantage of that approach is that a page access next to the previous one can reuse the CRST entries and needs just a single read from memory to create the page-table TLB entry. The disadvantage is that the TLB flushing rules are more complicated, before any page-table may be freed the TLB needs to be flushed. In short: the generic RCU page-table freeing code is incorrect for the CRST entries, in particular the check for mm_users < 2 is troublesome. This is applicable to 3.0+ kernels.

After investigation, it turns out TCP uses sk_stream_alloc_skb() and used as a convention skb_tailroom(skb) to know how many bytes of data payload could be put in this skb (for non SG capable devices) Note : these skb used kmalloc-4096 (MTU=1500 + MAX_HEADER + sizeof(struct skb_shared_info) being above 2048) Later, mac80211 layer need to add some bytes at the tail of skb (IEEE80211_ENCRYPT_TAILROOM = 18 bytes) and since no more tailroom is available has to call pskb_expand_head() and request order-1 allocations. This patch changes sk_stream_alloc_skb() so that only sk->sk_prot->max_header bytes of headroom are reserved, and use a new skb field, avail_size to hold the data payload limit. This way, order-0 allocations done by TCP stack can leave more than 2 KB of tailroom and no more allocation is performed in mac80211 layer (or any layer needing some tailroom) avail_size is unioned with mark/dropcount, since mark will be set later in IP stack for output packets.

The hypothesis is that the host never actually halted before the register write to change the event ring pointer to zero. Remove all writes of zeroed values to pointer registers in xhci_mem_cleanup(). Instead, make all callers of the function reset the host controller first, which will reset those registers to zero. xhci_mem_init() is the only caller that doesn't first halt and reset the host controller before calling xhci_mem_cleanup().

By the USB analyzer, I found the device finished the link training process and worked at superspeed mode. But the device descriptor got from the device shows the device works at 2.1. It is very strange and seems like the device controller of Seagate Goflex has a little confusion. The first 8 bytes of device descriptor should be: 12 01 00 03 00 00 00 09 But the first 8 bytes of wrong device descriptor are: 12 01 10 02 00 00 00 40 The wrong device descriptor caused the initialization of mass storage failed. After a while, the device would be recognized as a high speed device and works fine. This patch will warm reset the device to fix the issue after finding the bcdUSB field of device descriptor isn't 0x0300 but the speed mode of device is superspeed. This patch should be backported to kernels as old as 3.2, or ones that contain the commit 75d7cf72ab9fa01dc70877aa5c68e8ef477229dc "usbcore: refine warm reset logic".

While doing that, it also speeds them up by doing the accesses a word at a time. Finally, the new routines also properly handle the case of hitting the end of the address space, which we have never done correctly before (fs/namei.c has a hack around it for that reason). Despite all these improvements, it actually removes more lines than it adds, due to the de-duplication. Also, we no longer export (or define) the legacy __strncpy_from_user() function (that was defined to not do the user permission checks), since it's not actually used anywhere, and the user address space checks are built in to the new code. Other architecture maintainers have been notified that the old hack in fs/namei.c will be going away in the 3.5 merge window, in case they copied the x86 approach of being a bit cavalier about the end of the address space.

This is reported for two cases in https://bugzilla.kernel.org/show_bug.cgi?id=42775. The first case has the lock originating from within rtlwifi and could be fixed by rearranging the locking; however, the second originates from within mac80211.

Similarly for v4, on an open-create, return the same errors we would on an attempt to open a non-regular file, instead of returning nfserr_exist. This fixes a problem found doing a v4 open of a symlink with O_RDONLY|O_CREAT, which resulted in the current client returning EEXIST. Thanks also to Trond for analysis.

The reason for this revert is that making the frequency verification preemptible and interruptible is not working reliably. Michaels machine failed to use PM-timer with the message: PM-Timer running at invalid rate: 113% of normal - aborting. That's not a surprise as the frequency verification does rely on interrupts being disabled. With a async scheduled thread there is no guarantee to achieve the same result. Also some driver might fiddle with the CTC channel 2 during the verification period, which makes the result even more random and unpredictable. This can be solved by using the same mechanism as we use in the deferred TSC validation code, but that only will work if we verified a working HPET _BEFORE_ trying to do the PM-Timer lazy validation. So for now reverting is the safe option.

This can lead to a page leak as pages are pinned using get_user_pages, but only unpinned with put_page if they still exist in the memslots list on vm shutdown. A memslot that is destroyed while an iommu domain is enabled for the guest will therefore result in an elevated page reference count that is never cleared. Additionally, without this fix, the iommu is only programmed with the first translation for a gpa. This can result in peer-to-peer errors if a mapping is destroyed and replaced by a new mapping at the same gpa as the iommu will still be pointing to the original, pinned memory address.

Fix that by jumping to the 'err_free_mem' label at the end of the function that properly cleans up rather than returning directly.

There is exactly one user of irq_virq_count in-tree right now: PS3. Also, irq_virq_count is only useful for the NOMAP mapping. So, instead of having a single global irq_virq_count values, this change drops it entirely and added a max_irq argument to irq_domain_add_nomap(). That makes it a property of an individual nomap irq domain instead of a global system settting.

A side effect of that patch was that now also untiled objects have a non-zero obj->last_fenced_seqno to track when a fence can be set up after a pipelined tiling change. Unfortunately this was only cleared by the fence setup and teardown code, resulting in tons of untiled but inactive objects with non-zero last_fenced_seqno. Now after resume we completely reset the seqno tracking, both on the driver side (by setting dev_priv->next_seqno = 1) and on the hw side (by allocating a new hws page, which contains the seqnos). Hilarity and indefinite waits ensued from the stale seqnos in obj->last_fenced_seqno from before the suspend. The fix is to properly clear the fencing tracking state like we already do for the normal gpu rendering while moving objects off the active list. Reported-and-tested-by: "Rafael J.

While the fork is occurring (and thus we have marked all the PTEs as read-only), another thread in the original process (on cpu B) tries to write to a huge page, taking an access violation from the write-protect and calling hugetlb_cow(). Now, suppose the fork() fails. It will undo the COW and decrement the ref count on the pages, so the ref count on the huge page drops back to 1. Meanwhile hugetlb_cow() also decrements the ref count by one on the original page, since the original address space doesn't need it any more, having copied a new page to replace the original page. This leaves the ref count at zero, and when we call unlock_page(), we panic. fork on CPU A fault on CPU B ============= ============== ... down_write(&parent->mmap_sem); down_write_nested(&child->mmap_sem); ... while duplicating vmas if error break; ... up_write(&child->mmap_sem); up_write(&parent->mmap_sem); ... down_read(&parent->mmap_sem); ... lock_page(page); handle COW page_mapcount(old_page) == 2 alloc and prepare new_page ... handle error page_remove_rmap(page); put_page(page); ... fold new_page into pte page_remove_rmap(page); put_page(page); ... oops ==> unlock_page(page); up_read(&parent->mmap_sem); The solution is to take an extra reference to the page while we are holding the lock on it.

Before the commit, the code makes senses to me but not after the commit. The "nr_reclaimed" is the number of pages reclaimed by scanning through the memcg's lru lists. The "nr_to_reclaim" is the target value for the whole function. For example, we like to early break the reclaim if reclaimed 32 pages under direct reclaim (not DEF_PRIORITY). After the reverted commit, the target "nr_to_reclaim" is decremented each time by "nr_reclaimed" but we still use it to compare the "nr_reclaimed". It just doesn't make sense to me...

To prevent the leaks I consolidated all error exits from the function at a 'err:' label at the end and made all error cases jump to that label where we can then make sure we always free 'prz'. This is safe since all the situations where the code bails out happen before 'prz' has been stored anywhere and although we'll do a redundant kfree(NULL) call in the case of kzalloc() itself failing that's OK since kfree() deals gracefully with NULL pointers and I felt it was more important to keep all error exits at a single location than to avoid that one harmless/redundant kfree() on a error path.

It turns out that we don't load the free space cache if we're in a commit for deadlock reasons, but since we're reading the cache and it hasn't changed yet we are safe reading the inode and free space item from the commit root, so do that and remove all of the deadlock checks so we don't unnecessarily skip loading the free space cache.

Since the current hwmod sequence is accessing the sysconfig register just after the reset, it might lead to OCP bus error in that case. Add a new field in the sysconfig structure to specify a delay in usecs needed after doing a softreset. In the case of the ISS and FDIF modules, the L3 OCP port will be disconnected upon a SW reset. That issue was confirmed with HW simulation and an errata should be available soon. The HW recommendation to avoid that is to wait for 100 OCP clk cycles, before accessing the IP. Considering the worse case (OPP50), the L3 bus will run at 100 MHz, so a 1 usec delay is needed. Add an x2 margin to be safe.

The VENC interface previously had "dss_54m_fck" as it's clock which couldn't be autoidled, and hence the OCPIF_SWSUP_IDLE flag was needed. Remove the OCPIF_SWSUP_IDLE flag from VENC interfaces as it's clock is now "dss_ick". This allows the PRCM hardware to autoidle the VENC interface clocks when they are not active, rather than relying on the software to do it, which can keep the interface clocks active unnecessarily.

Platforms that wish to use the regulator API to manage their power domains can indirect via the power domain interface. This feature is only used with the vape supply of the db8500 PRCMU driver which supplies the UARTs and MMC controllers, none of which have support for managing vcore at runtime in mainline (only pl022 SPI controller does). Update that supply to have an always_on constraint until the power domain support for the system is updated so that it is enabled for these users, this is likely to have no impact on practical systems as probably at least one of these devices will be active and cause AMBA to hold the supply on anyway.

This was allowing there to be cases when phonenet was not initialized and the phonet net_generic was not set for a network namespace when network device events were being reported on the netdevice_notifier for a network namespace leading to the oops above. 2) phonet_exit_net was implementing a confusing and special case of handling all network devices from going away that it was hard to see was correct, and would only occur when the phonet module was removed. Now that unregister_netdevice_notifier has been modified to synthesize unregistration events for the network devices that are extant when called this confusing special case in phonet_exit_net is no longer needed.

When rt6_info.rt6i_flags has no RTF_EXPIRES flag,the dst.expires has no use. we can use this field to point to where the dst cache copy from. The dst.from is only used in IPV6. rt6_check_expired check if rt6_info.dst.from is expired. ip6_rt_copy only set dst.from when the ort has flag RTF_ADDRCONF and RTF_DEFAULT.then hold the ort. ip6_dst_destroy release the ort.

By calling netif_stop_queue() from ppp_start_xmit(), based on the return value from ppp_xmit_process() but *after* all the locks have been dropped, we could potentially do so *after* the channel has actually finished transmitting and attempted to re-wake the queue. Fix this by moving the netif_stop_queue() into ppp_xmit_process() under the xmit lock. I hadn't done this previously, because it gets called from other places than ppp_start_xmit(). But I now think it's the better option. The net queue *should* be stopped if the channel becomes congested due to writes from pppd, anyway. Signed-off-by: David Woodhouse Signed-off-by: David S.

In fact, doing so is a bug because if the trap occurred in the idle loop, this invocation can result in lockdep-RCU failures. The problem is that RCU ignores idle CPUs, and the sparc64 trap-return path to the softirq handlers fails to tell RCU that the CPU must be considered non-idle while those handlers are executing. This means that RCU is ignoring any RCU read-side critical sections in those handlers, which in turn means that RCU-protected data can be yanked out from under those read-side critical sections. The shiny new lockdep-RCU ability to detect RCU read-side critical sections that RCU is ignoring located this problem. The fix is straightforward: Make sparc64 stop manually invoking the softirq handlers. Reported-by: Meelis Roos Suggested-by: David Miller Signed-off-by: Paul E.

After further review, it was found such a reset can cause the 82579 to confuse which version of 82579 it actually is and broke LPLU on all 82577/8/9 devices. The workaround during an S0->Sx transition on 82579 (instead of resetting the PHY) is to restart auto-negotiation after the OEM bits are configured; the restart of auto-negotiation activates the new OEM bits as does the reset. With 82577/8, the reset is changed to a generic reset which fixes the LPLU bits getting set wrong.

The number of pending frames is stored as an 8 bits field in KS_RXFCTR. If interrupts are disabled long enough to allow for more than 32 frames to accumulate in the MAC's internal buffers, a buffer overflow occurs. This patch fixes the problem by making the driver's frame_head_info buffer big enough. Well actually, since the chip appears to have 12K of internal rx buffers and the shortest ethernet frame should be 64 bytes long, maybe the limit could be set to 12*1024/64 = 192 frames, but 255 should be safer.

First off, instead of retrying the writes for the BAR registers only, it did that for all of the PCI config space of the device, including the status register (whose value after the write quite obviously need not be the same as the written one). Second, it added arbitrary delay to pci_restore_state() even for systems where the PCI config space restoration was successful at first attempt. Finally, the mdelay(10) it added to every iteration of the writing loop was way too much of a delay for any reasonable device. All of this actually caused resume failures for some devices on Mikko's system. To fix the regression, make pci_restore_state() only retry the writes for BAR registers and only wait if the first read from the register doesn't return the written value. Additionaly, make it wait for 1 ms, instead of 10 ms, after every failing attempt to write into config space. Reported-by: Mikko Vinni Signed-off-by: Rafael J.

The default state of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing covert communication - eg between userspace tasks running inside chroot jails. This patch sets up TEECR in order to prevent user-space access to TEEHBR when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to access TEEHBR.

We know that 'count' is positive in 'long' (that is checked in the caller), so we will truncate 'max' down to something that fits in a signed long, but before we actually do that, that comparison needs to be done in unsigned. Bug introduced in commit 92ae03f2ef99 ("x86: merge 32/64-bit versions of 'strncpy_from_user()' and speed it up"). On x86-64 you can't trigger this, since the user address space is much smaller than 63 bits, and on x86-32 it works in practice, since you would seldom hit the strncpy limits anyway. I had actually tested the corner-cases, I had only tested them on x86-64. Besides, I had only worried about the case of a pointer *close* to the end of the address space, rather than really far away from it ;) This also changes the "we hit the user-specified maximum" to return 'res', for the trivial reason that gcc seems to generate better code that way. 'res' and 'count' are the same in that case, so it really doesn't matter which one we return.

Fix this by explicitly computing crtc timings in the lvds mode fixup function and setting a special flag in mode->private_flags if the crtc timings have been adjusted. v2: Add a comment to explain the new mode driver private flag, suggested by Eugeni Dodonov. v3: Kill the confusing and now redundant set_crtcinfo call in intel_fixed_panel_mode, noticed by Chris Wilson.

The incoming cpuidle driver uses the 'prcmu_enable_wakeups' and the 'prcmu_set_power_state' functions but these ones are defined but not implemented for the db5500, leading to an unresolved symbol error at link time. In order to compile, we have to disable the db5500 support which is not acceptable for the default config. I noticed there are also some other functions which are defined but not implemented. This patch fix this by removing the functions definitions and move out of the config section the empty functions which are normally used when the DB550 config is disabled. Only the functions which are not implemented are concerned by this modification.

If the PHYs are reset at during usbhs core driver, host ports will not work because EHCI driver is loaded after the resetting PHYs. The PHYs should be in reset state while initializing the EHCI controller.

Because efi_main() is always executed when booting from a boot loader we will dereference invalid pointers either on the stack (CONFIG_X86_32) or contained in %rdx (CONFIG_X86_64) when searching for an EFI System Table signature. Instead of dereferencing these invalid system table pointers, add a new entry point that is only used when booting from EFI firmware, when we know the pointer arguments will be valid.

The introduced condition for calling the fixup code is true for all AMD multi-node processors, e.g. Magny-Cours and Interlagos. There we have 2 NUMA nodes on one socket. Thus there are cores having different numa-node-id but with equal phys_proc_id. There is no point to print error messages in such a situation. The confusing/misleading error message was introduced with commit 64be4c1c2428e148de6081af235e2418e6a66dda ("x86: Add x86_init platform override to fix up NUMA core numbering"). Remove the default fixup function (especially the error message) and replace it by a NULL pointer check, move the Numascale-specific condition for calling the fixup into the fixup-function itself and slightly adapt the comment.

The problem was that the buffer of the trace_array was passed to the write function and not the trace array itself. The trace_array can change the buffer when running a latency tracer. If this happens, then the buffer being disabled may not be the buffer currently used by ftrace. This will cause the tracing_on file to become useless. The simple fix is to pass the trace_array to the write function instead of the buffer. Then the actual buffer may be changed.

But the ia64 implementation was subtly broken. Gcc does not know that register "r8" will be updated by the fault handler if the cmpxchg instruction takes an exception. So it feels safe in letting the initialization of r8 slide to after the cmpxchg. Result: we always return 0 whether the user address faulted or not. Fix by moving the initialization of r8 into the __asm__ code so gcc won't move it.

Wysocki" Date: Mon, 16 Apr 2012 23:07:50 +0200 Subject: PCI: Retry BARs restoration for Type 0 headers only Some shortcomings introduced into pci_restore_state() by commit 26f41062f28d ("PCI: check for pci bar restore completion and retry") have been fixed by recent commit ebfc5b802fa76 ("PCI: Fix regression in pci_restore_state(), v3"), but that commit treats all PCI devices as those with Type 0 configuration headers. That is not entirely correct, because Type 1 and Type 2 headers have different layouts. In particular, the area occupied by BARs in Type 0 config headers contains the secondary status register in Type 1 ones and it doesn't make sense to retry the restoration of that register even if the value read back from it after a write is not the same as the written one (it very well may be different). For this reason, make pci_restore_state() only retry the restoration of BARs for Type 0 config headers. This effectively makes it behave as before commit 26f41062f28d for all header types except for Type 0. Tested-by: Mikko Vinni Signed-off-by: Rafael J.

The WRED mode values had been previously held in the VQ for the default DP. After these values were moved to wred_set, the VQ for the default DP was no longer created automatically (so that it could be omitted on purpose, to have packets in the default DP enqueued directly to the device without using RED). However, gred_dump() was overlooked during that change; in WRED mode it still reads qavg/qidlestart from the VQ for the default DP, which might not even exist. As a result, this command sequence will cause an oops: tc qdisc add dev $DEV handle $HANDLE parent $PARENT gred setup \ DPs 3 default 2 grio tc qdisc change dev $DEV handle $HANDLE gred DP 0 prio 8 $RED_OPTIONS tc qdisc change dev $DEV handle $HANDLE gred DP 1 prio 8 $RED_OPTIONS This fixes gred_dump() in WRED mode to use the values held in wred_set.

A WARN_ON_ONCE() was added to __call_rcu() by: e56014000816 ("rcu: Simplify offline processing") to check for this condition. Although this condition did not trigger (at least as far as I know) during -next testing, it did recently trigger in mainline: https://lkml.org/lkml/2012/4/2/34 What is needed longer term is for RCU's CPU_DEAD notifier to adopt any callbacks that were posted by CPU_DYING notifiers, however, the Linux kernel has been running with this sort of thing happening for quite some time. So the only thing that qualifies as a regression is the WARN_ON_ONCE(), which this commit removes. Making RCU's CPU_DEAD notifier adopt callbacks posted by CPU_DYING notifiers is a topic for the 3.5 release of the Linux kernel. Reported-by: Sergey Senozhatsky Signed-off-by: Paul E.

This causes breakage on multiple boards using uart pins for alternate functions. For example, on zoom3 random oopses can be seen with nfsroot as the smsc911x ethernet FIFO timings on GPMC bus are controlled by gpmc_wait2 and gpmc_wait3 pins. This means we can't mux these pads to uart4 functionality as commit 7496ba3 was doing. Not all boards tend to use all uarts and most of unused uart pins are muxed for other purpose. This commit breaks the modules which where trying to use unused uart pins on their boards. So remove the default pad muxing. Note that this is not a complete fix, as we now rely on bootloader set muxing for the uart wake-up events. Further patching is needed to enable wake-up events for uarts that are already muxed to uart mode.

The task tries to lock the bandwidth_mutex at a time when it already owns the lock: The attribute's method calls usb_set_configuration(), which calls usb_disable_device() with the bandwidth_mutex held. usb_disable_device() unregisters the existing interfaces, which causes the hub driver to be unbound. The hub_disconnect() routine calls hub_quiesce(), which calls usb_disconnect() for each of the hub's children. usb_disconnect() attempts to acquire the bandwidth_mutex around a call to usb_disable_device(). The solution is to make usb_disable_device() acquire the mutex for itself instead of requiring the caller to hold it. Then the mutex can cover only the bandwidth deallocation operation and not the region where the interfaces are unregistered. This has the potential to change system behavior slightly when a config change races with another config or altsetting change. Some of the bandwidth released from the old config might get claimed by the other config or altsetting, make it impossible to restore the old config in case of a failure. But since we don't try to recover from config-change failures anyway, this doesn't matter.

A resume is needed when a port status change is detected, obviously, but only if the root hub is currently suspended. Right now the driver tests whether the root hub is running, and that is not the correct test. In particular, if the controller has died then the root hub should not be restarted. In addition, some buggy hardware occasionally requires the root hub to be running and sending out SOF packets even while it is nominally supposed to be suspended. In the end, the test needs to be changed. Rather than checking whether the root hub is currently running, the driver will now check whether the root hub is currently suspended. This will yield the correct behavior in all cases.

Then we use the RESIZE_IF_NEEDED macro on 'a' - this may free 'a->d' and replace it with newly allocaetd storage. In that case, we'll be operating on freed memory further down in the function when we index into 'ap[]'. Since we don't actually need 'ap' until after the use of the RESIZE_IF_NEEDED macro we can just delay the assignment to it until after we've potentially resized, thus avoiding the issue.

Linus spotted the clockevent handler being NULL. commit fa4da365b(clockevents: tTack broadcast device mode change in tick_broadcast_switch_to_oneshot()) tried to fix a problem with the broadcast device setup, which was introduced in commit 77b0d60c5( clockevents: Leave the broadcast device in shutdown mode when not needed). The initial commit avoided to set up the broadcast device when no broadcast request bits were set, but that left the broadcast device disfunctional. In consequence deep idle states which need the broadcast device were not woken up. commit fa4da365b tried to fix that by initializing the state of the broadcast facility, but that missed the fact, that nothing initializes the event handler and some other state of the underlying clock event device. The fix is to revert both commits and make only the mode setting of the clock event device conditional on the state of active broadcast users. That initializes everything except the low level device mode, but this happens when the broadcast functionality is invoked by deep idle.

Pentium Classic P5 and friends didn't have this MSR. MSR_IA32_APICBASE was introduced as an architectural MSR by Intel @ P6. Code paths that can touch this MSR invalidly are when vendor == Intel && cpu-family == 5 and APIC bit is set in CPUID - or when you simply pass lapic on the kernel command line, on a P5. The below patch stops Linux incorrectly interfering with the MSR_IA32_APICBASE for P5 class machines. Other code paths exist that touch the MSR - however those paths are not currently reachable for a conformant P5.

Paul bisected this regression. The conversion was done blindly and is wrong, as it does not provide a primary handler to disable the level type irq on the device level. Neither does it set the IRQF_ONESHOT flag which handles that at the irq line level. This can't be done as the interrupt might be shared, though we might extend the core to force it. So an interrupt on this line will wake up the thread, but immediately unmask the irq after that. Due to the interrupt being level type the hardware interrupt is raised over and over and prevents the irq thread from handling it. Fail. request_irq() unfortunately does not refuse such a request and the patch was obviously never tested with real interrupts.

In that function we have this code: ... ipath = init_ipath(size, root, path); if (IS_ERR(ipath)) { ret = PTR_ERR(ipath); ipath = NULL; goto out; } ... out: btrfs_free_path(path); free_ipath(ipath); ...

Updated BIOSes will have this new value set up from the beginning, but meanwhile we correct this value ourselves.

This leaves a window where this path is enabled, but we haven't synchronized the iommu mappings to the existing memory slots.

A processes address space is described by a struct mm_struct, and every thread has a pointer to the mm it should run in. The exception to this are kernel threads, which don't have an mm, and so borrow the mm from the last thread which ran. The system is bootstrapped by the initial kernel thread using init's mm (even though init hasn't been created yet, its mm is the static init_mm). The other feature is how the kernel handles the page table which describes the portion of the address space which is only visible when executing inside the kernel, and which is shared by all threads. On the SH4 the only portion of the kernel's address space which described using the page table is called P3, from 0xc0000000 to 0xdfffffff. This portion of the address space is divided into three: - mappings for dma_alloc_coherent() - mappings for vmalloc() and ioremap() - fixmap mappings, primarily used in copy_user_pages() to create kernel mappings of user pages with the correct cache colour. To optimise the TLB miss handler we don't want to add an additional condition which checks whether the faulting address is in the user or the kernel portion of the address space, and so all page tables have a common portion which describes the kernel part of the address space. As the SH4 uses a two level page table, only the kernel portion of first level page table (the pgd entries) is duplicated. These all point to the same second level entries (the pte's), and so no memory is wasted. The reference page table for the kernel is called the swapper_pg_dir, and when a new page table is created for a new process the kernel portion of the page table is copied from swapper_pg_dir. This works fine when changes only occur in the second level of the kernel's page table, or the first level entries are created before any new user processes. However if a change occurs to the first level of the page table, and there are existing processes which don't have this entry in their page table, this new entry needs to be added. This is done on demand, when the kernel accesses a P3 address which isn't mapped using the current page table, the code in vmalloc_fault() copies the entry from the reference page table (swapper_pg_dir) into the current processes page table. The bug which this patch addresses is that the code in vmalloc_fault() was not copying addresses which fell in the dma_alloc_coherent() portion of the address space, and it should have been copying any P3 address. Why we hadn't seen this before, and what made this hard to reproduce, is that normally the kernel will have called dma_alloc_coherent(), and accessed the memory mapping created, before any user process runs. Typically drivers such as USB or SATA will have created and used mappings of this type during the kernel initialisation, when probing for the attached devices, before init runs. Ethernet is slightly different, as it normally only creates and accesses dma_alloc_coherent() mappings when the network is brought up, but if kernel level IP configuration is used this will also occur before any user space process runs. So the first reproduction of this problem which we saw was occurred when USB and SATA were removed from the kernel, and then bring up Ethernet from user space using ifconfig. I'd like to thank Joseph Bormolini who did the hard work reducing the problem to this simple to reproduce criteria. In your case the situation is slightly different, and turns out to depends on the exact kernel configuration (which we had) and your ramdisk contents (which we didn't - hence the need for some assumptions). In this case the problem is a side effect of kernel level module loading. Kernel subsystems sometimes trigger the load of kernel modules directly, for example the crypto subsystem tries to load the cryptomgr and MTD tries to load modules for Flash partitioning if these are not built into the kernel. This is done by the kernel creating a user process which runs insmod to try and load the appropriate module. In order for this to cause problems the system must be running with a initrd or initramfs, which contains an insmod executable - if the kernel can't find an insmod to run, no user process is created, and the problem doesn't occur. If an insmod is found, a process is created to run it, which will inherit the kernel portion of the swapper_pg_dir first level page table. It doesn't matter whether the inmod is successful or not, but when the the kernel scheduler context switches back to the kernel initialisation thread, the insmod's mm is 'borrowed' by the kernel thread, as it doesn't have an address space of its own. (Reference counting is used to ensure this mm is not destroyed, even though the user process which caused its creation may no longer exist.) If this address space doesn't have a first level page table entry for the consistent mappings, and a driver tries to access such a mapping, we are in the same situation as described above, except this time in a kernel thread rather than a user thread executing inside the kernel.

A rather annoying and common case is when booting a PVonHVM guest and exposing the PV KBD and PV VFB - as broken toolstacks don't always initialize the backends correctly. Normally The HVM guest is using the VGA driver and the emulated keyboard for this (though upstream version of QEMU implements PV KBD, but still uses a VGA driver). We provide a very basic two-stage wait mechanism - where we wait for 30 seconds for all devices, and then for 270 for all them except the two mentioned. That allows us to wait for the essential devices, like network or disk for the full 6 minutes.

The broadcast device might be still in SHUTDOWN state when we actually need to use it. That obviously breaks, as set_next_event() is called on a shutdown device. This did not break on x86, but Suresh analyzed it: From the review, most likely on Sven's system we are force enabling the hpet using the pci quirk's method very late. And in this case, hpet_clockevent (which will be global_clock_event) handler can be null, specifically as this platform might not be using deeper c-states and using the reliable APIC timer. Prior to commit 'fa4da365bc7772c', that handler will be set to 'tick_handle_oneshot_broadcast' when we switch the broadcast timer to oneshot mode, even though we don't use it. Post commit 'fa4da365bc7772c', we stopped switching the broadcast mode to oneshot as this is not really needed and his platform's global_clock_event's handler will remain null. While on my SNB laptop, same is set to 'clockevents_handle_noop' because hpet gets enabled very early. (noop handler on my platform set when the early enabled hpet timer gets replaced by the lapic timer). But the commit 'fa4da365bc7772c' tracked the broadcast timer mode in the SW as oneshot, even though it didn't touch the HW timer. During resume however, tick_resume_broadcast() saw the SW broadcast mode as oneshot and actually programmed the broadcast device also into oneshot mode. So this triggered the null pointer de-reference after the hpet wraps around and depending on what the hpet counter is set to. On the normal platforms where hpet gets enabled early we should be seeing a spurious interrupt (in my SNB laptop I see one spurious interrupt after around 5 minutes ;) which is 32-bit hpet counter wraparound time), but that's a separate issue. Enforce the mode setting when trying to set an event.

On the platforms where broadcast timer is not really required, this will generate spurious broadcast timer ticks upon resume. For example, on the always running apic timer platforms with HPET, I see spurious hpet tick once every ~5minutes (which is the 32-bit hpet counter wraparound time). Similar to boot time, during resume make the oneshot mode setting of the broadcast clock event device conditional on the state of active broadcast users.

Call unregister_netdevice_notifier early so that the rest of the cleanup code does not need to deal with network devices. This takes advantage of my recent enhancement to unregister_netdevice_notifier to send unregister notifications of all network devices that are current registered.

If a specific platform needed additional busses probed, then it could call of_platform_bus_probe() again. Typically, the additional platform-specific busses are children of existing busses that have already been probed. of_platform_bus_probe() does not handle those child busses automatically. Unfortunately, this doesn't actually work. The second (platform-specific) call to of_platform_bus_probe() never finds any of the busses it's asked to find. To remedy this, the platform-specific of_device_id tables are eliminated, and their entries are merged into mpc85xx_common_ids[], so that all busses are probed at once.

This bug was caused by the creation of the dynamic length stack trace again (like commit 12b5da3 "tracing: Fix ent_size in trace output" was). This bug is caused by the latency tracers requiring the next event to determine the time between the current event and the next. But by grabbing the next event, the iter->ent_size is set to the next event instead of the current one. As the stacktrace event is the last event, this makes the ent_size zero and causes nothing to be printed for the stack trace. The dynamic stacktrace uses the ent_size to determine how much of the stack can be printed. The ent_size of zero means no stack. The simple fix is to save the iter->ent_size before finding the next event. Note, mirage335 asked to remain anonymous from LKML and git, so I will not add the Reported-by and Tested-by tags, even though he did report the issue and tested the fix.

That patch added a local "offset" variable to handle the offset, and then only updated the original "*poffset" before exiting. Unfortunately, it copied off the original offset from the beginning, instead of doing so after generic_write_checks had been called. Fix this by moving the initialization of "offset" after that in the function.

Consequently mmc_can_trim() is separated from mmc_can_discard(). Also the new discard operation does not result in the sectors being set to all-zeros, so discard_zeroes_data must not be set. In addition, the new discard has the same timeout as trim, but from v4.5 trim is defined to use the hc timeout. The timeout calculation is adjusted accordingly. Fixes apply to linux 3.2 on.

This uninlines (and rewrites it to be clearer) do_mmap(), which sadly duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have to export our internal do_mmap_pgoff() function. Some day we hopefully don't have to export do_mmap() either, if all modular users can become the simpler vm_mmap() instead. We're actually very close to that already, with the notable exception of the (broken) use in i810, and a couple of stragglers in binfmt_elf.

This makes sense, but the implementation detail of calling mmc_card_is_removable() causes some problems, because mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root filesystem is stored on SD, but we also have external SD card slots where we want automatic card detection. Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE, which is defined to mean that the card is *really* nonremovable. This could be revisited in future if we find a way to improve CONFIG_MMC_UNSAFE_RESUME semantics.

The interrupt handler schedules a workqueue which acquires a mutex that ks8851_net_stop() also acquires before flushing the workqueue. Previously lockdep wouldn't be able to find this problem but now that it has the support we can trigger this lockdep warning by rmmoding the driver after an ifconfig up. Fix the possible deadlock by disabling the interrupts in the chip and then release the lock across the workqueue flushing.

While EEH error happened to the PCI device without the corresponding device driver, kernel crash was seen. Eventually, I successfully reproduced the problem on Firebird-L machine with utility "errinjct". Initially, the device driver for Emulex ethernet MAC has been disabled from .config and force data parity on the Emulex ethernet MAC with help of "errinjct". Eventually, I saw the kernel crash after issueing couple of "lspci -v" command. The root cause behind is that the PCI device, including the reference to the corresponding eeh device, will be removed from the system while EEH does recovery. Afterwards, the PCI device will be probed again and added into the system accordingly. So it's not safe to retrieve the eeh device from the corresponding PCI device after the PCI device has been removed and not added again. The patch fixes the issue and retrieve the eeh device from OF node instead of PCI device after the PCI device has been removed.

Instead, just skip the whole timeout operation if we see that the timer is pending.

This was already handled on the kernel compat side, but it needs handling on the user space side, which uses the generic header. To make that possible: 1.

If, when md_notify_reboot gets the mddev lock, the array is in a state where it is assembled but hasn't been started (as can happen if the personality module is not available, or in other unusual situations), then incorrect metadata will be written out making it impossible to re-assemble the array.

That would be because of reclaim's shrink_page_list() calling add_to_swap() on this page at the same time: first PageSwapCache is set (causing page_mapping(page) to appear as &swapper_space), then page->private set, then tree_lock taken, then page inserted into radix_tree - so there's an interval before taking the lock when the radix_tree slot is empty. We could fix this by moving __add_to_swap_cache()'s spin_lock_irq up before the SetPageSwapCache. But a better fix is simply to do what's five years overdue: Ken Chen introduced __set_page_dirty_no_writeback() (if !PageDirty TestSetPageDirty) for tmpfs to skip all the radix_tree overhead, and swap is just the same - it ignores the radix_tree tag, and does not participate in dirty page accounting, so should be using __set_page_dirty_no_writeback() too. s390 testing now confirms that this does indeed fix the problem.

This may happen, for example, when the rindex is being updated by gfs2_grow. The gfs2_grow needs to have the lock in EX, but the other nodes need to re-read it to retrieve the updates.

Users have been forced to unbind or unload ehci-hcd before putting their systems to sleep. After extensive testing, it was determined that the machines don't like going into suspend when any EHCI controllers are in the PCI D3 power state. Presumably this is a firmware bug, but there's nothing we can do about it except to avoid putting the controllers in D3 during system sleep. The patch adds a new flag to indicate whether the problem is present, and avoids changing the controller's power state if the flag is set. Runtime suspend is unaffected; this matters only for system suspend. However as a side effect, the controller will not respond to remote wakeup requests while the system is asleep.

Calculate the number of required free pages based on non-high memory pages only, because that is where the buffers will come from. Commit 081a9d043c983f161b78fdc4671324d1342b86bc introduced a new buffer page allocation logic during hibernation, in order to improve the performance. The amount of pages allocated was calculated based on total amount of pages available, although only non-high memory pages are usable for this purpose. This caused hibernation code to attempt to over allocate pages on platforms that have high memory, which led to hangs. Signed-off-by: Bojan Smojver Signed-off-by: Rafael J.

This is because parse_args() puts a NUL in the string where the '=' was when it passes the "param" and "val" pointers to the parsing subfunctions. Previously, unknown_bootoption() was the last parse_args() subfunction to run, and it carefully put back the '=' character.

The comments above __alloc_bootmem_node() claim that the code will first try the allocation using 'goal' and if that fails it will try again but with the 'goal' requirement dropped. Unfortunately, this is not what the code does, so fix it to do so. This is important for nobootmem conversions to architectures such as sparc where MAX_DMA_ADDRESS is infinity. On such architectures all of the allocations done by generic spots, such as the sparse-vmemmap implementation, will pass in: __pa(MAX_DMA_ADDRESS) as the goal, and with the limit given as "-1" this will always fail unless we add the appropriate fallback logic here.

It won't change much for most people, already using acerhdf, as they use their own fanon/fanoff variable settings when loading the module. Furthermore seems like kernel and userspace tools have been improved to work more efficient and netbooks don't get so hot anymore.

If I understand the code correctly, we use the original mode unchanged for the output timings, safe for the lvds case. And we should use the adjusted mode for input timings. Clarify the situation by adding an explicit output_dtd to the sdvo mode_set function and streamline the code-flow by moving the input and output mode setting in the sdvo encode together. Furthermore testing showed that the sdvo input timing needs the unadjusted dotclock, the sdvo chip will automatically compute the required pixel multiplier to get a dotclock above 100 MHz. Fix this up when converting a drm mode to an sdvo dtd.

Due to questions raised in review, below a more elaborate analysis of the bug at hand: Sdvo seems to have two timings, one is the output timing which will be sent over whatever is connected on the other side of the sdvo chip (panel, hdmi screen, tv), the other is the input timing which will be generated by the gmch pipe. It looks like sdvo is expected to scale between the two. To make things slightly more complicated, we have a bunch of special cases: - For lvds panel we always use a fixed output timing, namely intel_sdvo->sdvo_lvds_fixed_mode, hence that special case. - Sdvo has an interface to generate a preferred input timing for a given output timing. This is the confusing thing that I've tried to clear up with the follow-on patches. - A special requirement is that the input pixel clock needs to be between 100MHz and 200MHz (likely to keep it within the electromechanical design range of PCIe), 270MHz on later gen4+. Lower pixel clocks are doubled/quadrupled. The thing this patch tries to fix is that the pipe needs to be explicitly instructed to double/quadruple the pixels and needs the correspondingly higher pixel clock, whereas the sdvo adaptor seems to do that itself and needs the unadjusted pixel clock. For the sdvo encode side we already set the pixel mutliplier with a different command (0x21). This patch tries to fix this mess by: - Keeping the output mode timing in the unadjusted plain mode, safe for the lvds case. - Storing the input timing in the adjusted_mode with the adjusted pixel clock. This way we don't need to frob around with the core crtc mode set code. - Fixing up the pixelclock when constructing the sdvo dtd timing struct. This is why the first hunk of the patch is an integral part of the series. - Dropping the is_tv special case because input_dtd is equivalent to adjusted_mode after these changes. Follow-up patches clear this up further (by simply ripping out intel_sdvo->input_dtd because it's not needed). v2: Extend commit message with an in-depth bug analysis.

There are exactly four users of __monitor and __mwait: - cstate.c (which allows acpi_processor_ffh_cstate_enter to be called when the cpuidle API drivers are used. However patch "cpuidle: replace xen access to x86 pm_idle and default_idle" provides a mechanism to disable the cpuidle and use safe_halt. - smpboot (which allows mwait_play_dead to be called). However safe_halt is always used so we skip that. - intel_idle (same deal as above). - acpi_pad.c. This the one that we do not want to run as we will hit the below crash. Why do we want to expose MWAIT_LEAF in the first place? We want it for the xen-acpi-processor driver - which uploads C-states to the hypervisor. If MWAIT_LEAF is set, the cstate.c sets the proper address in the C-states so that the hypervisor can benefit from using the MWAIT functionality. And that is the sole reason for using it. Without this patch, if a module performs mwait or monitor we get this: invalid opcode: 0000 [#1] SMP CPU 2 .. snip..

Commit 8ae8090c82eb407267001f75b3d256b3bd4ae691 (usb: gadget: udc-core: fix asymmetric calls in remove_driver) moved the usb_gadget_udc_stop() call in usb_gadget_remove_driver() below the usb_gadget_disconnect() call. As a result, usb_gadget_disconnect() gets called at a time when the gadget driver believes it has been unbound but dummy-hcd believes it has not. A nasty error ensues when dummy-hcd calls the gadget driver's disconnect method a second time. To fix the problem, this patch moves the gadget driver's unbind notification after the usb_gadget_disconnect() call. Now nothing happens between the two unbind notifications, so nothing goes wrong.

While that commit was technically the right thing to do, and made the x86-64 compat mode work identically to native 32-bit mode (and thus fixing the problem with a 32-bit systemd install on a 64-bit kernel), it turns out that the automount binaries had workarounds for this compat problem. Now, the workarounds are disgusting: doing an "uname()" to find out the architecture of the kernel, and then comparing it for the 64-bit cases and fixing up the size of the read() in automount for those. And they were confused: it's not actually a generic 64-bit issue at all, it's very much tied to just x86-64, which has different alignment for an 'u64' in 64-bit mode than in 32-bit mode. But the end result is that fixing the compat layer actually breaks the case of a 32-bit automount on a x86-64 kernel. There are various approaches to fix this (including just doing a "strcmp()" on current->comm and comparing it to "automount"), but I think that I will do the one that teaches pipes about a special "packet mode", which will allow user space to not have to care too deeply about the padding at the end of the autofs packet. That change will make the compat workaround unnecessary, so let's revert it first, and get automount working again in compat mode. The packetized pipes will then fix autofs for systemd.

When we are in the packetized mode (marked by O_DIRECT as suggested by Alan Cox), a write() on a pipe will not merge the new data with previous writes, so each write will get a pipe buffer of its own. The pipe buffer is then marked with the PIPE_BUF_FLAG_PACKET flag, which in turn will tell the reader side to break the read at that boundary (and throw away any partial packet contents that do not fit in the read buffer). End result: as long as you do writes less than PIPE_BUF in size (so that the pipe doesn't have to split them up), you can now treat the pipe as a packet interface, where each read() system call will read one packet at a time. You can just use a sufficiently big read buffer (PIPE_BUF is sufficient, since bigger than that doesn't guarantee atomicity anyway), and the return value of the read() will naturally give you the size of the packet. NOTE! We do not support zero-sized packets, and zero-sized reads and writes to a pipe continue to be no-ops. Also note that big packets will currently be split at write time, but that the size at which that happens is not really specified (except that it's bigger than PIPE_BUF). Currently that limit is the system page size, but we might want to explicitly support bigger packets some day. The main user for this is going to be the autofs packet interface, allowing us to stop having to care so deeply about exact packet sizes (which have had bugs with 32/64-bit compatibility modes). But user space can create packetized pipes with "pipe2(fd, O_DIRECT)", which will fail with an EINVAL on kernels that do not support this interface.

We first fixed that up by making the 64-bit compat mode know about this problem in commit a32744d4abae ("autofs: work around unhappy compat problem on x86-64"), and that made a 32-bit 'systemd' work happily on a 64-bit kernel because everything then worked the same way as on a 32-bit kernel. But it turned out that 'automount' had actually known and worked around this problem in user space, so fixing the kernel to do the proper 32-bit compatibility handling actually *broke* 32-bit automount on a 64-bit kernel, because it knew that the packet sizes were wrong and expected those incorrect sizes. As a result, we ended up reverting that compatibility mode fix, and thus breaking systemd again, in commit fcbf94b9dedd. With both automount and systemd doing a single read() system call, and verifying that they get *exactly* the size they expect but using different sizes, it seemed that fixing one of them inevitably seemed to break the other. At one point, a patch I seriously considered applying from Michael Tokarev did a "strcmp()" to see if it was automount that was doing the operation. Ugly, ugly. However, a prettier solution exists now thanks to the packetized pipe mode. By marking the communication pipe as being packetized (by simply setting the O_DIRECT flag), we can always just write the bigger packet size, and if user-space does a smaller read, it will just get that partial end result and the extra alignment padding will simply be thrown away. This makes both automount and systemd happy, since they now get the size they asked for, and the kernel side of autofs simply no longer needs to care - it could pad out the packet arbitrarily. Of course, if there is some *other* user of autofs (please, please, please tell me it ain't so - and we haven't heard of any) that tries to read the packets with multiple writes, that other user will now be broken - the whole point of the packetized mode is that one system call gets exactly one packet, and you cannot read a packet in pieces.
